Self-limiting electrolyte filling method

摘要

The invention relates to a method for producing an electrochemical cell, in particular a secondary battery or a double-layer capacitor, in which a cell vessel containing at least one porous cell component is filled with a flowable electrolyte. It is based on the object of providing a method involving simpler equipment that reacts to the fluctuating free volume with an adapted filling amount of electrolyte in the interests of optimum filling.;This object is achieved by providing that, in a first filling step, an excess amount of electrolyte is introduced, in which the porous cell component is completely immersed, that the electrolyte introduced is subjected to a force that drives out of the cell vessel the part of the electrolyte that is not located in the pores of the porous component and that, in a second filling step, an added amount of electrolyte is introduced.

1. A method for producing an electrochemical cell comprising:
first filling a cell vessel that contains at least one porous cell component with an excess amount of a flowable electrolyte that immerses the at least one porous cell component; exposing the cell vessel containing the flowable electrolyte to at least one force that drives out of the cell vessel a part of the electrolyte that is not located in the pores of the porous component; and then second filling the cell vessel with an additional amount of flowable electrolyte.
